Excellent Explanation My Dear❤
Thank you so much for the feedback.
💐💐💐
Great explanation
Thanks for the valuable comment.
Bhai, Electrical Engineering se related kon sa business start kre plz suggests me ideas???
U can start business related to electrical equipment or its assembly of products
With due respects sir, the frequency is not changed when the output voltage increases or decreases as compared to the required voltage. The switching transistor is switched off for outputs higher than the intended output. The frequency is constant normally & only the high & low times of the transistor are changed as per the output conditions ( duty cycle is changed). Correct me if am wrong sir. All in all your video is nice & likeable.
Ton and Toff is adjusted in pwm ....but he indeed was telling about variable frequency all the time...anyways by got the whole idea
Excellent Teaching Sir 🙏🙏🙏🙏👍....
Ur Welcome dear.
🌺🌺🌺
Very well explained.
Thanku...
thank you sir
Welcome dear.
💐💐💐
If the speech you described in the video was also written in the description box. that will better
Yes it's very beneficial
Thank you
When we getting DC output in last
So why we used switsh skt.& Transformer . we got the dc before switch skt.
To increase the Frequency we have used the Switching circuit.
Bht zbrdst
Thanks.
💐💐💐
Couldn’t have explained it better.
Thank you!!
Thankyou so much.
💐💐💐
Amazing
Superb❤❤❤❤
Thanks a lot dear.
💐💐💐
Sooo helpfull videoo need lot of like👍
Thank u very much...
Bhai ye frequency ko badhate kaise h...aur Dc ko phir se ac me kaise convert krte h
For increasing frequency we use chopper to convert fixed dc to variable dc, aur fir variable dc ko hum switching ckt ke sath freq increase karte hn
Good one sir...
Thanks a lot dear.
💐💐💐
Sir after t/f step down humko ka dc m tha na wave High frequency ac m kaise aaya jise phir se rectifier karna pada sir samjh nahi aaya ye point
B/c AC me high frequency obtain nhi kar sakte is convert kiya hn AC to DC me.
Aur fir PWM kar use karke high frequency obtain karte hn
Smps supply me components k option bhi maujood hote hai kya jisse poore circuit ki age or jyada badh sake
Instead of feedback, what if we use voltage regulator?
Hlo dear,
By using voltage regulator we can only regulate the voltage.
But by using feedback system we can compare the output voltage with desired value of voltage. and then we can use the error b/w them for desired switching pattern.
Thankyou.
💐💐💐
Sir apke ek request hai ki ap ek video banye types of smps ka
Sure Soon I will try to make video on it.
Ok sir
Thank u so much
Welcome dear.

I would like to develop one SMPS which will convert alternate inducted current into regular or pure DC. The value of input current is 12000V 7amp. How much we will get after using SMPS. My requirement is about 5000 to 6000 volts pure DC. Is it possible. Could you suggest me the diagram for the same.
Thanks sir.sir audio amplifier ke liye use kar sakte hai kya?
Thanks for the cmnt. Yes we can use it for Audio Amplifier, but before using once check the required dc vtg for the amplifier.
I have doubt bro the transformer is only used for AC supply inorder to transferring power one circuit to another and it can be either stepup or stepdown. I don't know doest it also used for DC supply.
Dc current se tranformer kya kaam krega
Mere pas 24 volt ka ek smps hai. Uski output ki negative aur positive dono me hi tester dene se jal raha hai. Ye smps thik hai ya kharab hai?
Dear check the output supply voltage via multimeter,
Aur mujhe lg rha hn shyad multimeter earth ho rha hn.
Hello sir gdmrng reference signal ke bare m apne baatya iska matlb ky h
Reference signal is nothing but its used for detection.
So we can compare the o/p Signals.
Hii!!!
I have doubt !! That the op of chopper is dc na !! Then how can we give it to transformer???
Dear,
Input of transformer is not dc, it is square wave AC Obtained by switched ckt and PWM Technique.
@@industrialsolutions8138 Ohhh!! Understood Sir .... We r giving Variable Dc to transformer which is help to create flux in transformer...hmm now understand
Dc me transfarmer kaise kaam karega
Can we use anything instead of PWM ?
Okhh
I will search it & then I will tell you.
And dc chopper is there to conver the 230dc to 24 dc ..here what is the process of transformer
Nice
Thanks a lot...
Kya 12 v 15 amp wale SMPS ko 6 amp. Wale female socket se aur 1 mm wale wire se chala sakte h ....
When the first rectifier has already converted the AC current into DC, why is the second rectifier required? What is its function?
Chopper ka output DC hota hai...ye transformer ka input kaise ho sakta hai??? Bata bhai
Thank-you dear for the Question.
Chopper (rectifier Ckt ) aur T/F ke beech me humne PWM technique ka use kiya with switching ckt, jisse DC waveform Square wave AC Waveform me convert ho jati hn aur fir use hum T/F ke I/p ko dete hn.
How the frequency will be increased in the ckt
Sir wo to samjh m aa gya but filter ke bd ripple reduce karne ke bd switch ckt m ja ke kaise dc ac m convert ho gya
Due to switch circuit,
Switch circuit ka kaam hi ON and OFF karna hota hn. Aaise switch ckt Ek cycle me on and next me off karke AC me convert karta hn.
Thanks soo much 🥰sir
Urs welcome.
Bs bs ek last question hai ki PWD ka hi use kyu karte h isme special
Sir chopper k bd ka wave form (-) me Q gya sir o to DC m h na
Good Question dear.
But Chopper ke baad humne DC Waveform ko Switching Ckt me provide kiya hn with PWM technique jisse DC Waveform Square wave AC me convert ho gai hn.
Aur (-) negative me aa gai hn.
Thank you.
Chopper output is variable DC how u apply this to step down t/f which works on AC
Sir ek smps hai jiske 5n60c MOSFET, 4148 diode, 9014,9015 transister , kuchh Rasistance kharab nikle the maine badal diye ...
Ab smps 24 volt ki jagah 9 volt out kar rahi hai
Feedback circuit bhi sahi hai.....
Kya problem hongi...bataye please..
Sir bs last question hai ki pwd ka use hi kyu karte h specially
It's ok clear ur all doubts.
On and off of switch is controlled by PWM. isliye hum PWM ka use karte hn.
after switching circuit how can you use transformer as the signal is already DC
Thanks a lot dear for the comment.
An that is not DC signal it is square wave AC
@@industrialsolutions8138 after filtering you have given the DC signal to switching ckt,. Is that DC signal is converting into square waveform through switching circuit?
Yess dear,
Actually we in SMPS we r using PWM technique along with switching ckt. For converting into sinusoidal square wave.
t/f ke baad dc ko rectifier me kyu dalna he jab vo dc he hai??
Thanks a lot for the question dear.
Actually o/p of T/F DC nhi hn vo Square wave AC ke form me hn.
Isliye humne again use rectifier me dala hn. To make it DC
Thankyou.
An sorry for late reply dear.
Sir Kiya me isko power electronics ke exam me 10 marks ke question me likh kr aa skta hu ?
Sure dear,
1.) First make the Block Diagram then Explain Each Block of diagram
2.) Then make working diagram and explain it.
3.) After that make Waveforms.
Book me bola hai noice jyada hoti hai
Sir proper circuit diagram nahi hai, proper circuit diagram lekar explain kare showing and explaining every section and components of the circuit diagram
Hlo Friend...
Thanks for ur feedback.
Soon I will try to give detailed explanation
@@industrialsolutions8138 thanks😊
T/F not work on DC supply so we use T/F before where AC are coming.....
a transformer doesnt work on dc voltage, that switch is used to replicate an AC supply
Why using the o/p rectifier?
We require a dc output, so we need to rectify & filter the ac output of the transformer.
T/F is always use in AC supply why are u giving Dc supply in the starting of chopper ?
Linear power supply kya hota hai sir? Aur iski jagah transformer kyu nhi use kr skte
Hme pta h Ki Transformer AC pr work karta hai to yah DC PE Kaise work kre ga
Thanks a lot for the comment dear,
An yess T/F works on AC not on DC. or vo dc nhi hn i.e Square wave AC. which is obtained by PWM technique.
Sir square wave AC HOTA h ya dc
@@juhigupta3777 if Square wave is alternating than it is AC
Sir ek advantage SMPS m it has a strong anti interference kyu hai
Sir plzzz reply me
Yess it's also advantage of smps but exact reason mujhe bhi nhi pta.
I am also searching agar apko mile to mujhe bhi btana.
Sir mujhe v ny pta isliye apse bol rahe hai
भाई कौन सा ट्रांसफर डीसी कन्वर्ट के बाद लगाया जाता है ।। Dc wave में तो ट्रांसफार्मर काम ही नही करता
That is specially designed transformer
i.e Flyback transformer.
Bhai aap jaise poochne vale aur is yotuber jaise batane vale aapko mai bata do tranistor us pure filter dc ko ac me convert kar deta hai
Battery se nikla DC current aur Smps se nikla DC current kaya same hota hai
PAC sat point kaise katata hai operating
Switching k baad negative dc kaise aya bhai?
Switch ckt convert DC to AC??
Yess Switch ckt aur PWM Technique se hum DC ko Square Wave AC me convert karte hn.
Transformer not works on dc right
Yes dear.
💐💐💐
How can work transformer in DC supply
Input to transformer is not Dc ,it is square waveform obtained by chopping
Sir filter ka kam kya hota hai
Filters separate karte hn frequencies from other within mixed frequencies.
In simple words filters removes harmonics from AC ckt & ripple from dc ckt.
Muze 48 volt-40 amp smps chahiye. kaha mil sakta he?
Amos low heat kyu generated karta h ye to para hoga na sir
Hnji
Because of low heat dessipated in regulatory transistor.
@@industrialsolutions8138 thanks 😊 sir
Sir smps m power supply alag alg part m divide karke Power supply provide kartwa h isliye na low heat generated karta h na
Nice one
That's too gud reason.
Thanks
Kya hum DC ko directly transformer m NH de Satya
Hlo friend...
No hum directly DC ko T/F me nhi de sakte b/c
In DC supply we cant get the alternating flux to be linked to the secondary. As the emf induced in secondary is directly proportional to the variation of flux in secondary. The core becomes saturated.
So it cant be fed with DC supply.
Sir ye high frequency m kyu work karta hai
High frequency me isliye work karte hn taki overall SMPS ka size reduce hojaye.
As Frequency increases Transformer size reduces so overall SMPS size chota hojata hn.
Thanks 😊 sir
Thanks for ur feedback
🤗...
Transformer ko Ac supply kiase de diya bhai...usko.ac supply kaha se diya
@Roshanraj hlo friend...
T/F ko ac supply diya hn through switching ckt and PWM Oscillator.
It's called Block diagram not the circuit diagram
Thankyou dear for correcting me
🙂🙂🙂.
How can transformer work on DC current in your VDO🤔
Thankyou so much for the question.
T/F ka I/p DC nhi hn, vo Square wave AC hn jo humne Switching ckt aur PWM Technique se obtain kiya hn aur fir T/f ko I/p diya hn.
Thank you.
An sorry for late reply.
Waveform drawn after chopper is wrong.
I didn't get the point what you explained isn't for beginners.
Sir smps ki working smz nhi ayi
sorry mare jawan tut gaye
Not enough explained. Disappointed and time waste.
Thanks for ur feedback friend
I will try to give more detailed video on SMPS.
Right
पहले ट्रांसफार्मर लगाओ फिर रेक्टिफायर लगाओ यार क्या बकवास वीडियो बना रखा है
Hlo friend,
Friend if we connect T/F first to 220 volts AC supply the size of T/F will be very big & so the smps size will also become bulky.
So we first convert it to DC and as we can not give DC voltage to T/F input, so we use chopper with technique of PWM to convert DC signal wave to Pulsating DC waveform and then we give it to T/F.
Bhai sahab please rectify your graph, please don't give wrong information...
Chopper is a device which converts fixed DC to Variable DC 2:19
Abbey tu ne kabhi power electronics padhi bhi hai yeh kya waveform bana hai switching circuit k baad teri waveform AC mai convert ho gayi. Tum logo ki problem yeh hee hai technical in-depth knowledge hoti hai na Jo waveform bana nee hai woh bana do. DC and AC waveform mai saach bata tujhe antar pata hai. Bhai kiss ko sirf overview Lena ho woh iss video ko dekh na agar yeh wali waveform bana kar aayo Gaye toh pakka zero millye ga
